Megnto Barcode + quickbook extension build.

Hi. I needed Barcode + quickbook extension. The barcode system where client can generate barcode and store the pricing, quantity & barcode, so that we can integrate with quickbook online. Just make sure that I can create new bar code for new product to be in inventory and it will update the ecoomerce site and quickbook as well then I can use the scanner to scan and make sale I need to create, store and replace ecoomerce site when I add new product, then able to do offline sales It should integrate when ecommerce when I add bar code it will update website and quantity When I sell physically not online as well it will update quantity So i needed magento expert who has expereinces in barcode + quickbook extension works. Thanks. Alex.
